I Patented Oct. 29, 1907.

To all ulhom t't may concern:-

,erence being had'th erein t0 the accompanying drawing.

This invention relates to improvements in gasolene carbureters, and is for use in connection with explosive justing the air supply automatically by the suction actionof the engine, and also manually independently of the action of the engine.

The accompanying drawings illustrate a sectional view through the improved carbureter Thegasolene is fed to the carbureter through a pipe .24 to a passage 25 which extends into the air passage way 26, and this passage-way 25 has a restricted outlet 27 whichisc'ontrolled by a valve 28 extending to the outside of the carbureter, and provided with an operating head29 by means of which the valve is adjusted.

" A lock-nut 30 serves to hold the valve 28 to its adjusted position.

Air is admitted to the carbureter through the inlet 34 which is preferably provided with a suitable gauze covering 35 Located in the 'passage 34 is a partition 36, and this partition is formed with an outer series of perforations 37, and an inner series of perforations 88,

the'combined area of .these perforations being in'excess of the required area to provide a maximum amount of air for the motorl Exending inward from this partition 36 is an annular member39, the inner face of .which is made conical as shown, the smallest diameter of the cone surface being at the outer end of said member. The air passages 37 in the partition 36' are located at a point outside of the said member 37, while the air passages 38 are at a point to communicate with. the interior of said member..

Located within the coneshaped member 39 is adiaphragm'4t), which serves to throttle the passage of the air through the openings 38. This diaphragm is held in the position shown'by ineans of a spiral spring 41, the diaphragm and the spring being supported by a suitable stem 43 which in turn is attached toa web 44. ris shown, this diaphragm is a fairly close fit to the interior of the smallend of the cone-shaped member 39, and hence serves to throttle or control the passage of the air through the openings 38'to the air passage 26 ofthe carburetei'. Formed in the diaphragm 40 is a series of small openings (about three in number) 42, so

around the saidunember.

by a longitudinally adjustable casting or sleeve 46' member 45 to limitthe amount of air which will pass This member 39 is carried whichscreti's around the end of the member 45 as shown at 47 to accomplish the adjusting oi the inner end 48 of the member 39 in respect to the end of the member 45, and is clamped in this position by means'of a bolt 49 passing through perforated lugs 50.

Below the gasolcne inlet 27 the carbureter is provided with a plurality of screens 51 placed within a" chamber 52, and this chamber has at its lower end a passage 53 which communicates with the inlet of the engine or engines to be supplied with the explosive mixture. The engine or the said inlet are not here shown, as they form no part of the present invention, and are not essential to a full understanding thereof.

In operation, the inner end of the member 39 is so adjusted as to provide the maximum area around its inner end for the passage of air, above which maximum area the diaphragm 40 is acted upon by the suction of the engine for providing or allowing an increased amount of air to pass to the carbureter through the interior of the member 39. When the suction of the engine is such that more air will be required than will pass around the coneshaped member 39 and through the small openings in the diaphragm 40, then the diaphragm, under the influence of the suction is drawn inward within the cone-shaped member to the extent 'required to admit the additional amount of air neces 'way 55 to and through the series of mixing screens 51 to the lower end of the chamber 52 and from this chamber to the inlet of the engine.

vture, and this is accomplished .by providing the chamher with a water-jacket 56 which may be placed in communication with the water-cooling system of the engine. i I

From the foregoing description, it will be observed thatthe passage ways 37 are in effect main passageways for the air, and the passage ways 38 are auxiliary passage-ways, and for the convenience of generic expressions, these passage-ways ill be so designated in the claims.

.Having thus described my invention, what I claim and desire tosecure by Letters Patent, is:

1. An improvedcarburetor, comprising n. mixing chamber, gasolcnc and air inlet passages in communication therewith, the air inlet passage having an annulnr meniber therein constructed to form a main air passage-way thcrcaround, auxiliary passage-ways in communication with the interior of the annular member, and'u member normally obstructing the passing of air through the auxiliary passage and adapted to be moved away from said passages under the influence of the engine, for the purpose described.

2. An improved carburetor comprising a mixing cham' her having gasolene and air passages--1n communication therewith. the air passage having an adjustable annular member around which is formed a main air passageway, auxiliary passages in communication with the interior of the annular member, and means located within the-annular member for controlling the passage of the air through the aiwillary passag'wwa s.

3. A n improved carburetor including a mixing chamber having gas-alone and air inlet passages in communication therewith, an annular member within the'air passage-way and constructed to form a main air passage thercaround, auxiliary :hll' passages in cmumunication with the interior of the annular member, and means controlling the passage of air through the auxiliary passageways.

4. An improved carburetor comprising a mixing chamber having gasolene and air inlet passages in communication therewith, the air inlet passage having an annular member therein and constructed to form a main air passage therearound, theinterior wall of the annular member being concshapcd in cross-section, the cone diverging inwardly, auxiliary air passages in communication with the interior of the annular member, and an inwardly-movable diaphragm within the annular member and adapted to obstruct the passage of air through the auxiliary passages, the diaphragm adapted to be moved inward longitudinal the annular member by the suction of the engine.
